The present invention provides: a method for producing a capacitor element, the method involving an aging step (A) in which a voltage 1/3 to 4/5 of a formation voltage is applied to a capacitor element, on which a conductor is formed, under conditions in which the temperature is 15-50°C and the humidity is 75-90%RH; or a method for producing a capacitor element, the method involving, before the aforementioned step (A), a step (B) for retaining a capacitor element, on which a conductor is formed, under conditions in which the temperature is higher than 50°C and equal to or lower than 85°C and the humidity is 50-90%RH. According to this production method, it is possible to improve the LC properties of a tungsten solid electrolytic capacitor element having a carbon layer. |
